BRICK-MOLD 'CONVEYIN AND DUMPING APPARATUS.

To all whom 'it may concern.'

Be it known that I, WILLiAM E..Loouis, of the city of Sherbrooke, in theProvince of Quebec and Dominion of Canada, have invented certain newanduseful Improvements in Brick-Mold Conveying and Dumping Apparatus, ofwhich the following is aV full, clear, and exact description.

This invention relates to improvements in mold conveying and dumpingapparatus and the main object is to provide a simple and inexpensivedevice which will automatically .pick up the filled molds as they areejected from the brick machine, convey the same to a suitable point andthen dump the plastic material out of tlie molds without mutilating thesame.

A further object is to provide means whereby the plastic material willbe prevented from escaping prematurely from the molds and whereby thematerial from each mold' will be dumped onto a separate pallet.

A still further object is to provide a device which will return theemptied molds to the sander operated in conjunction with the brickmaking machine.

To accomplish these objects I rovide a. conveyer adapted to receive thefil ed molds from the brickv machine and deliver them to a secondconveyer operating at right angles to the first. At the point ottransfera 'pallet 'is positioned over each mold and is then carried therewith toa dumping table, the mold andv pallet being inverted during The mold isnow lifted ofil the pallet by the conveyer and dropped into the sander,the contents of the mold remaining on the pallet.

In the drawings which illustrate my invention Figure 1 is a sideelevation of the device. Fig. 2 is a plan view of the same. Fig. 3,1isan enlarged sectional detail view of the dumping mechanism on line 3 3of F ig. 2. Fig.4 is an enlarged detail view of one of the carriersattached to the conveyer chains.

In the above defined figures, 5 indicates f the location of a brickmaking machine and 6 the location of the sander operatin in connectiontherewith. A table 7 is provided over which the filled molds 8 ass asthey are ejected from the brick machine. A conveyer table 9 is locatedat right an les to the table 7 and on the same horizonta plane therewithso that the filled molds will pass Bpwetin ef hmm Patent' Patented Aug.30, 1910. application med June so, 190e. serial No. 505,172.

parallel with the conveyertable 9, and adjacent the side thereof remotefrom the brick machine, on which the empty pallets 13 are placed, facedown, as they are removed from the brick drying kiln. A air of endlessconveyer chains 14 are provided runnin at right angles to the conveyerchain 10. chains 14 pass over a pair of driving s rocktes 15 mounted ona shaft 16, journa ed to the framework 17 of the main p ortion of themachine, and over guiding sprockets 418, 19, 20, 21 and 22 arranged inpairs on shafts 23 journaled to the framework 17, parallel with thedrive shaft 16.

The chains 14 and sprockets may be arranged in various Ways but I preferthe arrangement shown in the drawings in which the chains run from thedriving sprockets 15 over the guide sprockets 18 and 19, the latter ofwhich, 19, are adjacent the outer side of the, pallet feed table. Fromthe sprockets 19 the chains run horizontally across the ends of thepallet feed table and conveyer or mold feed table 9 to the s rockets 20which are slidably mounted on rackets 24 in order that the chains may betensioned as'desired. The chains 14 run dia onally upward from thesprockets 20, the direction of motion of the dia onally moving portionbeing the reverse othe direction of the horizontally movin portion, tothe sprockets 21 and then horizontallyl to the sprockets 22, thedirection of travel being again reversed, so that the two horizontalportions move in the same direction. From the sprockets 22 the chainsrun downwardly to the drive sprockets 15, thus completing the circuit.The two chains 14 run parallel with each other and are such a distanceapart -that the molds and pallets may be placed lengthwise between themwithout touching either.

dumping tab e extends into the framework 17 the inner end thereof beingsupported scafo-:fl

by a strap 26 and the outer end by a pedestal 2T. The inner ends of the,guides 2: lie between the sprockets Q0 and are curved to correspondwith the curvature of the circumference of the sprockets. A metal' strap28 is fixed to the upper edge of each guide and follows the curvature ofthe inner ends thereof, so that the straps are bent around on themselvesin a semicircle et the same diameter as the sprockets 20. The strapsextend from the bends along under the guides 25, parallel therewith,across the mold feed table v9 and are then sloped upwardly and attachedat their extremities to the under sides of the guides. A plurality ofcarriers 29 are attached to the chains at regular intervals, thecarriers on one chain being opposite those on the other chain wherebythe molds may be held between the chains by the carriers. Each carriercomprises a fiat strip of metal, 30 bent into the forni of the letter U,an attaching member 3l fixed there to and a pallet catch 32. The arms ofthe U-shaped member 30 are ol vunequal length and are both pointed, thepoints being; at the outer sides 33, so that the inner sides 34- aretapered oli at The attaching member 3l is lixed to the longer arm ot'the` member 30 at the outer side 33 in order that when the carrier isattached to the chain leithe larger portion of the carrier will overhangthe chain. The pallet catch 32 is to the shorter arm of thc Uehapedmember at the outer edge and extends away from the point of the arm andthen transversely so that the upwardly turned extremity thereof will lieinside the inner side of the member 30. rThe carriers are made right andlett hand so that when placed on the chains 1,4 they will overhang* thechains toward each other iny order that the molds and pallets may beengaged and vcarried thereby without Contact with either chain. The endsof each mold boX are provided with projecting` lugs 36 adapted to beengaged between the arms of the Ll-shaped members to enable the moldboxes to be carried between the chains le, independent of any othersupport.

When the mold boxes 8 are ejected from the brick machine they pass overthe table 7 and onto the mold lfeed table 9, where they are caught oneat a time and carried into the framework l? by the catches l1 of thechain 10. The chain l0 disengages from the mold box when the same hasbeen carried to a position between the ychains le. Simultaneously withthe travel of the mold box on the mold feed table the catches 32 carriedby the chains le engage a pallet on the pallet feed table and carryl italong the arm 12a of the table to a position over the mold box, thepallet sliding under the straps 28 which press it tightly down on themold box. lt will be seen in the drawings, Figs. l and 3, that the arml2a of the pallet feed table is 1 as they are lled on a level with thetop of the mold i'eed table so that the pallet will slide asil y ontothe mold box lying in position on the mold feed table, "When the palletis in position over the mold box the arms ot the carriers 28 engage thelugs 3G on the ends of the .ir-.old box and carry it along` under thepallet, the pallet being held in place over the mold box by the catches32 and the straps 28. The mold box and pallet are carried by the chainsle over the sprockets 20 so that they inverted, the pallet lying .taceup on the guides 25 forming thedumping table while the mold box liesupside down on. the pallet. During the passage around the sprockets 20the semicireular bends in the straps 28 hold the pallet rinly againstthe mold box so that the clay therein will not fall out during theinversion. The chains le, which travel diagonally upward from thesprockets 20 to the sprockets 2l, carry the inverted mold box with themso that the same is gradually lifted from the pallet and the clayYcontents allowed to remain on the pallet in the exact form of the mold.Dinh ing the lift of the mold box the catches remain in engagement withthe pallet and slide it along' the guides .keeping it directly ander themold box until the latter is lifted above and entirely tree from thedischarged material, thus preventing the lower edge of the mold box fromshearing or scraping ott a portion of the discharged niateirial.Immediately after the mold. box is lilted above the discharged clay theupward movement of the chains disengagcs the Aches 32 from the pallet sothat the same is left stationary on the guides Q5 and ready to berenn'ived and'conveyed to the dry kiln with the molded clay thereon. Theempty mold bei; is carried by the-chains 14 over the sprockets and alongand over the sprockets 22. After passing over the sprockets 22 thechains take a downward direction and the lugs 36 on the mold box slipout from between the arms of the carriers 28 so thatV the mold box isdisengaged from the chains and falls 'oy gravity into the sander.

The chains of the device may be driven directly from the brick machineor from some other source and geared to operate at such a .speed thatthe mold boxes are dumped and dropped into the'sander es fast by thebrick making machine. lhe chain l0 may be driven directly from the brickmachine or may be geared to i the drive shaft 16 of the damper, aslshown in dotted lines.

' lt will be obvions from the foregoing description and drawings thatthe device disl closed will attain the objects setfoi'th and that theplastic clay will be removed from the .mold boxes without being in anyway mutilated and will be delivered from the apparatus in sach a formvthat it may he les,
